Niobium Atom Diagram
Particles:
Name: Niobium
Number of Protons: 41
Number of Neutrons: 52
Number of Electrons: 41
Atomics:
Atomic Number: 41
Atomic Mass: 92.90638 AMU
Melting Point: 2,468 degrees Celsius
Boiling Point: 4,927 degrees Celsius
The measurement, AMU, "Is used to express the mass of atoms and molecules," according to sizes.com/units. It is the equivalency of 1.660538782 X 10 to the power of −27 kilograms.
Discovery:
Charles Hatchett
Year of Initial Discovery: 1801
Original Discoverer: Charles Hatchett
Obtained from Columbium
It was originally discovered by Charles Hatchet in 1801, who discovered Columbium. The ore was sent to England in the 1750s by John Winthrop, who was the first governor of Connecticut. It was rediscovered by Heinrich Rose and Jean Charles in 1846 as an element found in Columbium. Christian Blomstrand first "prepared" the metal in 1864.
Name Origin:
Niobium was named after Niobe, daughter of the mythical king, Tantalus.
What is a Transition Metal?
Cubic Crystal Structure
Niobium is classified as a transition metal. There are 38 transition metals in the periodic table. Transition metals are, "the transition elements are both ductile (manageable) and malleable (moldable), and conduct electricity and heat," according to chemicalelements.com. These elements have valence electrons, or electrons that causes elements to combine, are present in more than one shell. Other transition metals include iron, nickel, and cobalt.
Crystal Structure:
A crystal is the structure of the molecule; the crystal structure of Niobium is cubic. The cubic crystal structure means that the atoms are arranged in a cube; although, perfect cubic molecules are very rare. Cubic structures are easy to bend and distort, such as Niobium.
Other Information:
Density: 8.57g/cm3
Color: Silvery Gray
Interesting Facts:
It is the 33rd most common element in the earth's crust
It is a solid at room temperature (20 degrees Celsius)
It is most commonly used in equipment that leaves Earth
Isotopes:
Isotopes are molecules where one of the atoms have the same atomic mass, but a different number of neutrons.

Steel Alloys
Uses:
Niobium is often used in tantalum capacitors, steel alloys, tantalum plating, hot metal spraying, arc welding, and super-conductivity research. Niobium commonly used on lenses and it may be used in generators because it conducts eletricity.
